(svn_txdelta__vdelta): When the destination of a copy straddles the source/target boundary, we were failing to output an opcode for the part of the copy which wrote target data.  Bug discovered using random input testing and an assertion in text_delta.c's apply_instructions() which compared the length of the regenerated output against tview_len.
